谢谢大家！ End of the Lecture * This sort of invention has become common enough that the United States Patent and Trademark Office (USPTO) has made an official policy of refusing to grant patents for perpetual motion machines without a working model. The USPTO granted a few patents for motors that are claimed to run without net energy input. These patents were issued because it was not obvious from the patent that a perpetual motion machine was being claimed. These are: Johnson, Howard R., US4151431 Permanent Magnet Motor, April 24, 1979 Baker, Daniel, US4074153 Magnetic propulsion device, February 14, 1978 Hartman; Emil T., US4215330 Permanent magnet propulsion system, December 20, 1977 (this device is related to the Simple Magnetic Overunity Toy (SMOT)) * Arthur Stanley Eddington From Wikipedia, the free encyclopedia ??(Redirected from Arthur Eddington) Jump to: navigation, search Arthur Eddington Arthur Stanley EddingtonBorn28 December 1882)Kendal, EnglandDied22 November 1944 (aged?61)Cambridge, EnglandResidenceEnglandFieldsAstrophysicistInstitutionsUniversity of CambridgeAlma materUniversity of CambridgeManchester UniversityDoctoral advisorsee belowDoctoral studentsLeslie ComrieKnown?forEddington limitEddington numberEddington-Dirac numberNotable awardsRoyal SocietyRoyal Medal (1928)Smiths Prize (1907)Royal Astronomical Society Gold MedalBruce MedalKnighthood (1930)Order of Merit (1938)Religious stanceQuakerNotesEddington received an MA in 1909 and did not have a doctorate or doctoral advisor.

The Eddington limit, the natural limit to the luminosity of stars, or the radiation generated by accretion onto a compact object, is named in his honour. He is famous for his work regarding the Theory of Relativity. Eddington wrote a number of articles which an
